Accordingly, even when there are foreign materials such as dust between movable contact parts 164 a and fixed terminals 162 , movable contact parts 164 a and fixed terminals 162 slide against each other and, consequently, can remove the foreign materials in contacting portions between movable contact parts 164 a and fixed terminals 162 .
  • card detection switch 160 A and writing possibility/impossibility detection switch 160 B are normal open switches in connector 100 according to the present embodiment, the present invention is not limited to this and may employ normal close switches. In this case, insertion of card is detected when fixed terminals 162 is parts from movable terminals 161 upon insertion of the card.
  • memory card 20 with electrodes 21 is fitted in connector 100 by way of insertion according to the present embodiment and electrodes 21 are electrically connected with contact pins 170 , any electronic component may be fitted in connector 100 as long as it can be inserted and electrically connected with connector 100 .
  • the connector according to the present invention provides an advantage of adequately detecting a state of an electronic component such as a memory card which is fitted by way of insertion, even when scrapes of a housing are produced due to insertion and removal of the electronic component which is fitted by way of insertion, and is useful for a memory card connector in particular.
